'YARN CLEANER.

f Application fat-(1v october 30, 192e.

To all whom t may concern:

Be it known that I, Lotus B. HAsnnoUoK, a citizen of the United States,residing at Elmira, in the county of Chemung and State of New York, haveinvented certain new and useful Improvements in Yarn Cleaners, fullydescribed and represented in the following` specification and theaccompanying drawing, forming a part of the same.

This invention relates to yarn cleaners for removing impurities fromtraveling yarns, and aims to provide a simple and effective device fordetaching specls and other impurities from a traveling yarn andcontinuously discharging such impurities from the cleaner.

Yarn cleaners heretofore made have been provided with transverse bladeshaving operating edges adjacent to the yarn and designed to detachimpurities from the yarn by a scraping action, or by a scraping andbrushing action. It has been found that when such edges are set in closecontact to the yarn so as to have the most effective scraping action,the fibrous matter which is inevitably scraped from the yarn With theimpurities tends to Wind about the yarn in front of the scraping edges.This results in forming rings of fiber about the yarn which increase insize until they become reattached to the yarn, forming bunches or slubson the yarn which detract from its usefulness. y

I have discovered that this difficulty may be altogether eliminated byplacing a smooth surface opposite the edges of the transverse blades andpositioning this surface so that it is in contact. with one side of theyarn while the edges of the blades contact with the other side of theyarn. The distance between the edges ofthe blades and the smooth surfacemay be made less than the normal diameter of the yarn so that the bladescontact firmly with the yarn and have an effective scraping action;While, at the same time, the smooth surface lies in close contact withone side of the yarn and thus positively prevents any fiber which may beloosened from the yarn from passing around the yarn to form rings andbunches. As the result, the impurities With any fiber which may beattached to them are effectively discharged from the cleaner.

by the travel of the yarn across their edges.

In order that the various features and advantages of the invention mayclearly be understood, I will describe in detail a speci fic yarncleaner embodying the invention in a form which I have found effective.Such a cleaner is shown in the accompanying drawings; in which Fig. 1 isa plan view of the cleaner;

Fig. 2 is a sidey vieiv of the cleaner sectioned on the line 2 2 of Fig.1;

Fig. 3 is an enlarged transverse section of the cleaner taken on theline 3 8 of Fig. 1;

Fig. 4 is a fragmentary horizontal section of the line 4 4 of Fig. 3;and

Fig. 5 is a perspective view of one of the blades of the cleaner.

The yarn cleaner illustrated has a rectangular frame 1() which may beprovided With a bracket 11 for supporting the frame from a horizontalrod 12. The frame has a fixed side 13 and a movable or adjustable side14. The ends 15, 16 of the frame may be made integral With the fixedside 13 of the frame. A tension device 17 is secured to the front end 15of the frame, that is, the end at which the traveling yarn enters thecleaner. The inside of the side 13 provides a smooth flat verticalsurface 2O and the ends 15 and 16 have recesses 21, 22 in their uppersurfaces positioned to permit a yarn A, which has been passed throughthe tension device, to be drawn longitudinally across the frame and incontact with the surface 20.

Cleaning and deflecting elements 30 are mounted on the movable side 14of the frame, extend inwardly therefrom, and are provided With operativeedges 31 lying in a common vertical plane parallel to the surface 20. Inorder that these edges may be brought into firm contact with the yarn AWhich is drawn along the surface Q0 regardless of the size of theparticular yarn to be cleaned, the side 14 is mounted so that itsdistance from the fixed side 13 of the frame .may be nicely adjusted.The means by which this adjustment is secured constitute a part of thepresent invention.

The front and rear ends 15, 1G of the 'trame 10 are provided at theirouter ends with vertical surfaces 40, 41 which are inclined at the samesmall angle to the fixed side 13 ot the frame. The movable side 14 isprovided with end portions 42, 43 which have inner surfaces 44, 45 whichare inclined to the side 14 at the same angle as that at which thesurfaces 40, 41 are inclined to the side 13. r1`he side 14 is secured tothe ends 15, 1G with its surfaces 44, 45 in contact with their surtaces40, 41, by means ot screws 4G which pass through longitudinal slots 47in end portions oit the side 14. By loosening the screws 4G the side 14may be adjusted endwise in either direction. llt/*hen it is moved towardthe trout end ot the cleaner it is brought slightly further from thetixed side 13, and when moved rearwardly it is brought slightly nearerto the side 13. The inclination ot' the inclined surt'aces is so slightthat tightening ol' the screws 46, after the proper adjustment has beenobtained, does not cause longitudinal movement of the side 14.Furthermore, because ot the tact that the inclined surfaces are allinclined at the same angle, adjustment ot the side 14 does not changethe angle between the side 14 and the side 13. Inail adjustments ot theside 14, theretore, the edges 31 of the elements 30 are all at aunit'orm distance troni the surface Q0.

ln the form shown, each cleaning and dellectiug element consists ot asingle piece oitl sheet metal Forming a blade Sli! and a resilientsupport S3. The outer end portion ot the resilient support 3S is set ina transverse slot 34 in a movable side 1lot" the trame. It is held inthis slot by means o't a washer 35 which forced down by a screw lti. Theresilient support 33 extends straight inward 'trom the side 14 ot' theframe, while the blade 32 extends transversely to the line et travel ot'the yarn and is inclined rearwardlyv from the vertical at an angle otabout 35. The operative edge 31 ot the blade 5l?, is straight andperpendicular to the resilient support 33. and is inclined to the lineot travel of the yarn by reason ot the inclination o't the blade. Theoperative edge 31 is made acute by forming a` beveled surface 3T on therear side of the blade. To tacilitate threading, the upper corner ot theedge 3l ot the blade 32 is rounded ott' at 38.

Each of the cleaning` and det'lecting elements 30 is free to vibratethrough the bending ot its resilient support rlhe bending of eachresilient support occurs principally at the part o1: the support justinside the side 14 of the frame. Consequently' when the edge 31 et oneof the blades 32 is struck by .a particle projecting from the ever, eachot' the blades is inclined to the vertical axis about which it turns,the lower end of its edge 31 moves outwardly from the surface 2O to agreater extent than the upper portion of its inner edge. As a resultwhen one ot the resilient supports 3S is bent rearwardly, the operativeedge 31 ot the blade instead ot lying parallel to the surte/e Q0, as inits normal position, diverges trom the surface 2O toward its lower end.

A plurality of pins extend inwardly trom the side 13 of the trame. Theupper surfaces ot these pins lie in the same hori- Zontal plane as thelower ends of the recesses 21, so that the pins prevent the yarn tromdropping below the blades 4Q when the cleaner is threaded, or in casethe yarn is slacliened in the course ot the operation oli the cleaner.

'ln using the device which has been described, the position ot the side14 is nrst adjusted to' make the distance between the edges S1 and thesur't'ace Q0 slightly less than the. normal diameter ot the yarn to becleaned. so that both the edges 31 and the surface Q0 will be in tirmcontact with the yarn when it is drawn through the cleaner. rlhe edgesare, however, not set close enough to the surface Q0 to pinch the yarnor to e-Lert a material drag or tension on it'.

Vlin the operation ol the device the yarn is drawn through the cleanerin the direction ot the arrow in Figs. l and by means ot' a spooling,winding, or other machine not shown in the drawings. The travel ot theyarn across the edgeso't the blades sets the blades into vibration, andthe edges ot the blades detach specls and other impurities lrom the yarnby a scraping and brushing` action. Since the surface 20 is in tirmcontact with the yarn, it positively prevents any fiber removed trom theyarn by the edges trom winding around the yarn and becoming reattachedto it. Consequently, the dirt removed trom the yarn, together with alllibrous matter removed with it, is deflected downwardly by the bladesand con t'inuously discharged at the bottom olf theI cleaner. The slightoutward turning;` ot the blades which occurs in their vibration preventsany tiber from beconiing caught between the edges of the blades and thesnrace 20.

Since, owing to the presence of the sur- Jface 20, the edges of theblades may be placed in tirm cont-act with the yarn withfit) ltlfl llOout danger' of causing loose fibers to entwine about the yarn in frontof the edges, the scraping action of the edges is very effectiveL-soeffective, indeed, that in some cases the brushing action of the edgesis not needed, and, in consequence, the supports of the blades may bemade rigid instead of resilient. Thus, While the vibration of the bladespossesses advantages, I have found that certain types of yarn may beefficiently cleaned when rigidly mounted blades are used in combinationVwith the surface 20. I Wish it understood, therefore, that my inventionin its broadest aspect includes the use of blades so mounted; and, inother respects, also, is by no means limited to the specific form andarrangement of the parts of the illustrative embodiment Whichlhas beendescribed.

Certain features of the device illustrated and described in thisapplication form a part of the subject matter of my co-pendingapplications Serial No. 582,384, filed August 17, 1922, and Serial No.671,745 filed Oct. se, 1923.
